Communism is the idea of "can't we all just get along?" which is obviously not something you can actually implement, but is easily used as a buzzword by evil regimes. Remember, H-tl-r called his regime "socialist", much the same way N-rth K-rea calls itself "democratic"
Every day you make comments that are downvoted (and probably flagged) by several people... I think it's quite possible that the real issue is not "other people."
Usually people who feel (or are) targeted are not 100% innocent.
There's a clear pattern where comments containing certain words are flagged much more often than comments containing mildly cens-red versions of those words. Could be HN itself but if we assume HN isn't lying about how its algorithm works (a big assumption) then it must be user flag bots.
It's not just my comments - you see something similar with headlines on the front page that contain certain names like El-n M-sk. They will accumulate hundreds of points and comments and then be cens-red.
That’s actually the point of libertarianism, anarchism: do what you want, but you will only do well if you get along with the rest of the society by providing something helpful to them, as no one is forced to help you. And that’s why free market capitalism works. Even the most selfish individuals have needed to cooperate, work for others or open businesses with useful products for society in order to be able to accumulate wealth.
